Bravado got the better of me yesterday and I foolishly volunteered to try to run 5km in sub-20.30.
As I started running on the machine at lunchtime, I finally worked out the speed I would need to do to achieve this: 9.4mph for 3.125 miles. Eeeek!
I thought I had better warm up thoroughly, so completed one mile before increasing the speed. After one more mile I can’t say that I felt particularly like doing 2.125 more at that speed, so I backed off.
So, Andy, the answer is no. Unfortunately I forgot to check what the time was when I did complete the 5km, so I’ll have to try again next week.
However, as I reached 5 miles, I noticed that the time was 38.44, which is actually faster than earlier in the week. This 7.74mph average speed would give me a 5km split time of just over 24 minutes. This is faster than I thought, bearing in mind it included my first warm-up mile.
